[ikiwiki] / doc / setup.mdwn

This tutorial will walk you through setting up a wiki with ikiwiki.

1. [[Download]] and [[install]] ikiwiki.

2. Decide where your wiki's files will go.

   As a wiki compiler, ikiwiki builds a wiki from files in a source directory,
   and outputs the files to a destination directory.  If you keep your wiki in
   a version control system, the source directory will contain a working copy
   checked out from the version control system.

   For the purposes of this tutorial, we'll set shell variables
   for these locations, and use those variables in the commands that follow.

                        SRCDIR=~/wikiwc
                        DESTDIR=~/public_html/wiki/

   Note that ikiwiki owns the working copy directory; do not perform your own
   edits in ikiwiki's working copy.

3. Create the beginnings of your wiki.

   This will create a simple main page for the wiki.

                        mkdir $SRCDIR
                        cd $SRCDIR
                        $EDITOR index.mdwn

   In the editor, you could start by entering a simple page like 
   [[toggle id=page text="this one"]].
   
   [[toggleable id=page text="""
                        Welcome to your new wiki.
                        All wikis are supposed to have a [[SandBox]],
                        so this one does too.
                        ----
                        This wiki is powered by [ikiwiki](http://ikiwiki.info).
   """]]
   
   See [[HelpOnFormatting]] for details about the markup language.

   Note that several [[standard_wiki_pages|basewiki]] will be added to your
   wiki, from files in `/usr/share/ikiwiki/basewiki/`, so your wiki will
   automatically get a [[SandBox]], and some other useful pages.

4. Build your wiki for the first time.

                        ikiwiki --verbose $SRCDIR $DESTDIR --url=http://example.org/~you/wiki/

   Replace the url with the real url to your wiki. You should now
   be able to visit the url and see your wiki.

5. Repeat steps 3 and 4 as desired, editing or adding pages and rebuilding
   the wiki. 
   
   To quickly get started on a common task like blogging with ikiwiki, you
   can copy in files from the [[examples]]. The examples are located in
   `doc/examples/` in the ikiwiki source package.

   You can play around with other ikiwiki parameters such as `--wikiname`
   and `--rebuild` too. Get comfortable with its command line (see
   [[usage]]).

6. By now you should be getting tired of typing in all the command line
   options each time you change something in your wiki's setup. Time to
   introduce setup files.
   
   A sample setup file is [[ikiwiki.setup]]. Download it (or copy it from
   `doc/ikiwiki.setup` in the ikiwiki sources), and edit it. Note that this
   file should *not* be put in your wiki's directory with the rest of the
   files. A good place to put it is in a ~/.ikiwiki/ subdirectory.
   
   Most of the options, like `wikiname` in the setup file are the same as
   ikiwiki's command line options (documented in [[usage]]. `srcdir` and
   `destdir` are the two directories you specify when running ikiwiki by
   hand. Make sure that these are pointing to the right directories, and
   read through and configure the rest of the file to your liking.

   When you're satisfied, run `ikiwiki --setup ikiwiki.setup`, and it
   will set everything up.

7. Turn on additional features.

   Now you have a basic wiki with a configuration file. Time to experiment
   with ikiwiki's many features. 
   
   Let's first enable a key wiki feature and set up [[CGI]] to allow
   editing the wiki from the web. Just edit ikiwiki.setup, uncomment the
   block for the cgi wrapper, make sure the filename for the cgi wrapper
   is ok, run `ikiwiki --setup ikiwiki.setup`, and you're done!

   There are lots of other configuration options in ikiwiki.setup that you
   can uncomment, configure, and enable by re-running
   `ikiwiki --setup ikiwiki.setup`. Be sure to browse through all the
   [[plugins]]..

8. Put your wiki in revision control.

   At this point you might want to check your wiki in to a revision control
   system you can get history of past changes and revert edits. Depending
   on the revision control system you choose, the way this is done varies.
   
   There's little that's ikiwiki specific about these instructions; this is
   just how you put a directory under revision control using the various
   systems that ikiwiki supports. Note that the .ikiwiki subdirectory is
   where ikiwiki keeps its state, and should be preserved, but not checked
   into revision control.

                        svn mkdir file://$REPOSITORY/trunk -m "create trunk"
                        cd $SRCDIR

   [[toggle id=git text="Git"]]
   [[toggleable id=git text="""
        When using Git, you probably want to set up two repositories, of which
        one should be bare (meaning that it does not have a working tree
        checked out). We call the bare repository the "repository" and the
        other will be the "srcdir" (which `ikiwiki` uses to compile the wiki).
        There are [other
        ways](http://blog.madduck.net/vcs/2007.07.11_publishing-git-repositories)
        to do the following, but this might be easiest:

                        REPOSITORY=~/wiki.git
                        GIT_DIR=$REPOSITORY git --bare init --shared
                        cd $SRCDIR
                        git init
                        echo /.ikiwiki > .gitignore
                        git add .
                        git commit -m "initial commit"
                        git remote add origin $REPOSITORY
                        git config branch.master.merge refs/heads/master
                        git push --all

        It is **paramount** that you **never** push to the Git repository in
        `$SRCDIR` ([this FAQ entry explains
        why](http://git.or.cz/gitwiki/GitFaq#head-b6a3d85f677763313159eb39f7dbf4579d4ee28b)).
        Instead, if you want to work on the wiki from a remote machine, clone
        `$REPOSITORY`, using either the `git` transport (if available), or
        `ssh`.

        If at any point you commit changes in `$SRCDIR`, make sure to `git
        push` them to the `$REPOSITORY`.

9. Configure ikiwiki to use revision control.

   Once your wiki is checked in to the revision control system,
   you should configure ikiwiki to use revision control. Edit your
   ikiwiki.setup, and uncomment the lines for the revision control system
   you chose to use. Be sure to set `svnrepo` to $REPOSITORY, if using
   subversion. Uncomment the block for the wrapper for your revision
   control system, and configure the wrapper path in that block
   appropriately (for Git, it should be `$REPO/hooks/post-update`).

   Once it's all set up, run `ikiwiki --setup ikiwiki.setup` once more.
   Now you should be able to edit files in $SRCDIR, and use your revision
   control system to commit them, and the wiki will automatically update.
   And in the web interface, RecentChanges should work, and files changed
   by web users will also be committed using revision control.
